The S5 No-MooMenu is one of the most advanced menu systems for Joomla! Unlike
other similar menu systems that use mootools and cause script conflictions with
your modules and components the S5 No-MooMenu is completely powered by S5
Effects so your modules and components won't cause any conflictions using this
menu system. Just mouse over the top menu and you will notice the menu smoothly
expand and fade in.
